Early habituation of severe blepharoptosis in Marcus Gunn jaw-winking syndrome
Ocular Motility Disorders
Ophthalmologic Surgical Procedures
A 23-day-old neonate had severe unilateral Marcus Gunn jaw-winking syndrome (MGJWS). By 2 1/2 months of age, she controlled the ptosis with jaw positioning. Habituation of the pterygoid-levator synkinesis has not been reported this early. Surgery can be delayed until a safer time in MGJWS with severe ptosis that lacks objective signs of amblyopia.
